It's seem your three spots were claimed so I'm probably a bit late here.

Though I'd like to warn against the 3 person limit, often what happens in RP's is players stop posting may it be they lost interest (right at the start often even) or other plans come up. So setting a limit of accepted players can put you in odd situations when players start leaving for certain reasons. This get's especially bad when the group is as small as four people.
